When using GL_EXT_vulkan_glsl_relaxed, check to see if a
uniform already exists in the block uniform block, and if so,
ensure they are the same type. Otherwise, avoid growing the block
with a duplicate.

globalUniformBlock->getWritableType().getQualifier().layoutSet = globalUniformSet;

+ if (memberType != symbol->getType()) {

+ err += "\"" + memberType.getCompleteString() + "\"";
+ err += " versus ";
+ err += "\"" + symbol->getType().getCompleteString() + "\"";
+ error(loc, "Types must match:", memberType.getFieldName().c_str(), err.c_str());

// Add the requested member as a member to the global block.
TType* type = new TType;
type->shallowCopy(memberType);
